* autoreconf.sh: Do not run autoheader if AC_CONFIG_HEADER is
	commented out in configure.in. Reported by Erez Zadok
	<ezk@cs.columbia.edu> as a fix for autoconf/21.

Usage: autoreconf [OPTION] ... [TEMPLATE-FILE]
Run \`autoconf' (and \`autoheader' and \`automake', where appropriate)
repeatedly to remake the Autoconf \`configure' scripts and
configuration header templates in the directory tree rooted at the
current directory. By default, it only remakes those files that are
older than their predecessors. If you install a new version of
Autoconf, running \`autoreconf' remakes all of the files by giving it
the \`--force' option.
-m, --macrodir=DIR directory storing macro files
-l, --localdir=DIR directory storing \`aclocal.m4' and \`acconfig.h'
-f, --force consider every files are obsolete
-v, --verbose verbosely report processing
-h, --help print this help, then exit
--version print version number, then exit
The following options are passed to \`automake':
--cygnus assume program is part of Cygnus-style tree
--foreign set strictness to foreign
--gnits set strictness to gnits
--gnu set strictness to gnu
-i, --include-deps include generated dependencies in Makefile.in
Report bugs to <bug-autoconf@gnu.org>."
